The Snare Wire (.5mm Size 3) is a slightly thicker surgical wire used in ENT (ear, nose, and throat) procedures, particularly for the removal of polyps, small tumors, or foreign bodies from the nasal cavity, sinuses, or throat. The .5mm thickness indicates that the wire is stronger than finer wires, making it suitable for removing larger growths or when more tension is needed to cut through tougher tissue.
